Safety Packaging Instructions

Custom Packaging Information

This packaging complies with national chemical safety standards, ensuring complete sealing, moisture resistance, leak prevention, and strong pressure resistance throughout the entire process. All packaging features a double-layer structure consisting of a paper-plastic composite outer bag and a PE inner liner, which effectively blocks moisture, isolates impurities, and prevents caking caused by humidity.
The packaging strictly complies with the international regulations governing the storage and transportation of hazardous chemicals for export, ensuring compression resistance, impact resistance, and leak-proof sealing to minimize damage during warehousing and the ocean transportation.

We can flexibly customize packaging and labels based on customers' purchase volumes, application scenarios, and international export standards. From inner liners to compliant shipping marks and hazard warnings, every detail is tailored to your needs. We support a complete range of packaging options, from small-batch reagent-grade vials and bottles to industrial bags, standard drums, and IBC containers. All options are designed to meet specific requirements across different purchase volumes, warehousing, logistics, transportation, and export customs clearance. This ensures comprehensive compliance with all regulatory and operational requirements, including safe storage, efficient shipping, and accurate trade documentation.
